Without checking for failures, I might add.

Let's call that regression/obvious bug #4, because the previous code actually CARED if the resource was reserved.

if (legacy_mode & ATA_PORT_PRIMARY)
pci_request_region(pdev, 1, DRV_NAME);
if (legacy_mode & ATA_PORT_SECONDARY)
pci_request_region(pdev, 3, DRV_NAME);
/* If there is a DMA resource, allocate it */
pci_request_region(pdev, 4, DRV_NAME);

I agree this is one way to avoid conflicts! ;-)
